911 calls capture drama of Fla. kidnapper's 100 mph police chase, report says

(CBS) LAKELAND, Fla. - A man who allegedly kidnapped his ex-girlfriend made chilling 911 calls during a 100 mph police chase in Florida and threatened to kill the woman and himself, reports CBS affiliate WTSP.

"911, where is your emergency?" a dispatcher is heard asking in recordings released by the Volusia County Sheriff's office. Brett Curtis, 28, calmly replies, "If the officer following me does not break off pursuit, then people will be hurt."

"You're risking this woman's life," Curtis says sternly during another 911 call. "We're heading south on I-95, you've got three officers ganging up on me right now. And I have enough ammunition to kill her and myself."

To show how serious he is, he put his terrified hostage, his 26-year-old ex-girlfriend, Elizabeth Hamilton, on the phone.

"I have been kidnapped and we are being followed," Hamilton said, gasping. "And he is gonna maybe kill me if they keep following him!"

Police say Curtis fired a gun out of his car, but missed the cops on his tail, reports WTSP.

Three gunshots can be heard in one 911 recording, followed by Curtis shouting into the phone, "Get off of my a-- now!"

When a dispatcher suggests, "Sir, why don't you pull over so we can end this peacefully?," Curtis cuts him off, saying, "That's not gonna happen!"

Police in Lakeland first learned of the abduction through a call from Hamilton's mother. She said her daughter went missing Monday evening from her job at a day spa at Lakeland Square Mall, reports the station.

"She went out the employees' entrance, and actually found her daughter's purse and personal belongings laying on the floor," Lakeland Police Sgt. Richard Rose said. "So that's what immediately caused her to have some concern about what might have happened."

Eight hours later, across the state in Volusia County, authorities spotted Curtis' car thanks to a statewide alert sent out by Lakeland Police.

Curtis reportedly refused to pull over for police, so officers chased him at speeds reaching 100 miles per hour, for around 30 miles. The pursuit stretched from South Daytona in Volusia County down into Brevard County.

It was during that chase that Curtis made the 911 calls.

Stop Sticks spread out across I-95 eventually blew out his tires and as the car stopped, Hamilton jumped out and ran to safety, according to the station, which says that Curtis fatally shot himself.

Authorities have not commented on a possible motive in the abduction.

A judge had reportedly approved a temporary injunction to keep Curtis away from Hamilton. She was scheduled to be in court on Tuesday to talk with a judge about making that temporary injunction a permanent one.
